Core Skills ​

Impact Highlights ​

• Regular DR / resilience drills at TrendMicro (every six months to quarterly, 5–6+ over tenure) across multiple core services
• Led the Airflow 1.x → 2.0 upgrade (UAT + Production, carrying many DAGs)
• Built a multi-channel event-driven FAST monitoring platform (CloudWatch → SNS → Lambda → Slack / LINE, Terraform IaC)
• High concurrency / scale: RDS Proxy absorbing bursts of thousands of connections, Aurora read replicas, SQS for high-volume orders
• Cloud cost optimization: EC2 RIs / Fargate Spot ~20% each, MediaLive Reservations ~50%

SRE / Reliability Core Competencies ​

• Kubernetes platform: built an EKS reference environment with rolling upgrades; standardized deployment with Kubernetes, Ansible, Gitea / Jenkins
• Observability: FAST-channel monitoring platform, DynamoDB dashboard + DevOps Guru anomaly detection, centralized ELK logging, end-to-end (E2E) monitoring
• Reliability / SRE: cross-service incident response, multiple DR / resilience drills, service readiness reviews; pre-commit / PR-gate guardrails in production workflows
• High concurrency / scale: RDS Proxy absorbing bursts of thousands of connections, Aurora read replicas, Redis 5 → Valkey 7 upgrade, SQS for a major telco partner's high-volume orders
• Led the team's coding-agent toolchain evolution (command → plugin → skill); built knowledge-base and account & secrets management skills for DevOps / SRE automation
• Built a knowledge-base automation pipeline (raw → distill → semantic search) integrated with Jira / Notion to speed up incident analysis and documentation

Experience ​

Staff DevOps Engineer · CATCHPLAY @@ 2024.04 – Present ​

• Built a multi-channel event-driven FAST monitoring platform (CloudWatch → SNS → Lambda → Slack / LINE, alert heatmaps, automated weekly reports, Terraform IaC); strengthened observability with a DynamoDB dashboard and DevOps Guru
• Co-built an EKS reference environment with AI-assisted guardrails (pre-commit secret scan, PR gates, layered secret scanning)
• Re-architected the data layer: Aurora read replicas, MySQL / PostgreSQL parallel operation, RDS Proxy (bursts of thousands of connections), Redis 5 → Valkey 7 upgrade (cost + EOL, some legacy systems retained); led the Airflow 1.x → 2.0 upgrade (UAT + Production, many DAGs)
• Sole owner of the GitLab → Gitea migration (hundreds of repos, the whole engineering org, < 2h off-peak cutover); built Serverless Lambda Terraform modules and Jenkins automation; developed geo-block deployment automation in Go
• Used SQS to handle a major telco partner's high-volume order throughput
• Integrated AWS Elemental streaming (DRM, Global Accelerator, SPEKE, IVS); migrated Akamai LDS → DataStream 2 via IaC
• Multi-cloud governance and security: GCP permission tightening, Secrets Manager credential cleanup, DRM / WAF / CVE audits; audited and cleaned up idle EC2 snapshots; client-project environments and CDN network allowlists

Senior SRE Engineer · TrendMicro @@ 2021.09 – 2024.03 ​

• Owned cross-service incident response; ran regular disaster-recovery drills (resilience testing, every six months to quarterly, 5–6+ over tenure across multiple core services) and maintenance windows
• Built end-to-end (E2E) monitoring and established a service readiness review process
• Drove the Opsworks → ASG / SSM migration; audited and decommissioned idle resources to cut cloud cost and tune logging

Senior DevOps Engineer · GoFreight @@ 2020.10 – 2021.09 ​

• Built EKS (Kubernetes) for high availability and rolling upgrades; replaced dev / stage environments with containers
• Introduced ELK for centralized logging; ran unit tests in the CI/CD pipeline to improve reliability
• Cut cost with EC2 RIs / right-sizing; upgraded MySQL 5.6 → 8.0 and upgraded the DMS engine
• Added autoscaling Jenkins workers for peak load

Senior DevOps Engineer · CATCHPLAY @@ 2019.02 – 2020.10 ​

• Created a one-click CI/CD pipeline for multi-environment deployment; built a stress-test environment (Locust / JMeter) to locate performance bottlenecks
• Replaced cron jobs with Airflow scheduling; refactored part of the ETL automation
• Standardized components via containers (multi-layer images)
• Centralized log management with ELK + Curator; tuned Logstash parsing rules
• Cut cloud cost with EC2 Spot / RIs; consolidated multi-source logs with Lambda

Senior Java / DevOps Engineer · Groundhog Tech @@ 2017.11 – 2019.02 ​

• Introduced Kubernetes, Ansible, and GitLab CI/CD; deployed DSP / DMP systems with improved performance and security
• Maintained and extended the CovMo signal-optimization system; refactored code and tuned SQL queries

Early Career @@ 2012 – 2017 ​

• Bank SinoPac · Senior Java Web Engineer (2015 – 2017): built an investment-workflow system and RESTful web services from scratch (Java backend)
• Gping / Gobooks · System Engineer (2012 – 2015): firewall & network topology, Acronis backup, Windows AD / Exchange, VMware HA + P2V
